This invention relates to new and useful Figure 1 is a front view .of the device with means for retaining a tuck made in a sleeve, the clamps n open pos1t1on.

Figure 3'is a front view'of the device with '55 The object of this invention is to provide the clamps in closed position.

The other ends of the oscillating memclamping action is not dependent upon a bers 7 are formed with eyes 8, guided on the spring. By this device the length of a sleeve ring 1. The length of these hinged oscillatcan be expeditiously shortened and it can be ing members 7 is somewhat smaller than the rendered simple, easy and convenient. ing 2 for these members 7 the ring 1 has 111- According to this invention, a ring, curvatlons 4 bemg nearly so proportmnedi through which a tuck or pleated part of a that the eyes 8 of the osc1llatmg members 7 sleeve is drawn, has hinged to it two hinged are placed in the clamping position in the other, said clamping jaws being thus adaptputting the ring 1 out of shape as shown in ed to grip the bunched aart of the sleeve be- Figure 3.

After having drawn the tuck ring, on which these members are guided. or pleated part of the sleeve through the ring The ring with its incurvations serves there- 1 between the clamping jaws 3, the oscillatas a guiding member for t e sliding ends of pressed agamst each other, whereby the ring the oscillating members and as an elastic 11s put out of its normal shape, that means,v locking device for these members. Preferit will take a form accord ng to Figure 2.

ably the inward bent incurvations of the which can be compared with an ellipse caused ring are formed slantingly to each other so by the length of the oscillating members 7 95 that a good clamping is also possible, if the being shorter than the diameter of the ring 1. leated part is thicker than usual. In the operative position, that is to say the A constructional example of the tuck or clamping position, the oscillating members pleat holder is shown in the accompanying 7 reach the incurvations 1, so that the ring 1 drawings in which: may spring back to its normal shape, thereby released by the incurvations 4 of the ring and caused to move apart by means of the bunched material. thereby releasing the pleated part.

Further the parts of the device can be made of curved or other suitable formation to conform to the arm as shown in Figure 4, and other modifications maybe adapted which do not exceed the scope of the invention.
